Abstract: A retention assembly for handling cyclical axial loads is disclosed. The retention assembly comprises a bearing, a motor, and a bushing element. The bearing is mounted around an axis of a shaft The motor is adapted to operate the shaft through a coupler. The bushing element is mounted around the axis of the shaft. The bushing element has a hollow cylindrical configuration defining an internal volume for accommodating the coupler and a portion of the shaft therein. An internal diameter of the bushing element is larger than an external diameter of each of the coupler and the shaft respectively. One end of the bushing element is in a contacting relationship with the bearing. The bushing element is adapted to hold the bearing in place through an interference fit with a motor housing ID for withstanding the cyclical axial loads.
